Revised Chain and Escalator Step Chain,Comprising a plurality of link units interconnected in series with each other, each of the link units comprising pairs of inner links in parallel with each other, arranged in pairs and in parallel with each other for connecting two adjacent link units And a steel wheel rotatably provided on the steel wheel shaft, characterized in that the link unit further comprises a traction main wheel, the traction main The wheel is provided on the steel wheel shaft and the outer diameter of the traction main wheel is larger than the outer diameter of the steel wheel. Since the outer diameter of the traction main wheel is larger than that of the steel wheel, the steel wheel plays a supporting role when the cascade Chain is driven by the drive steel wheel, and the main wheel takes the active action, so that the violent friction between the steel wheel and the transmission wheel can be avoided , Significantly extending the service life of the steel wheel and effectively protecting the transmission wheel, and the noise in the cascade chain movement is significantly reduced.
